Also be aware guys that, without exception, the WOP3 birds are researched with not only the Pilot's Notes (POH, if you like) but with the E&M's as well. Often the Pilot's Notes will give slightly vague or imprecise information that can sometimes be misleading (the US notes less so than the British), after all, they are for Pilots, not engineers. With the E&M's the aircraft can literally be assembled or torn down, piece by piece and these clarify any misleading information and give the exact lengths, volumes etc etc. Often several different versions are examined and changes tracked as there are often variations between serial ranges of the same model and more often between manuals for the SAME aircraft at different dates!! (As and aside, the AVG took British manuals to China as they had "hijacked" British allocated Tomohawks...so their manuals are quite unlike the equivalent US manuals)
As an example, I re-read almost my entire collection of Spitfire PN's and E&M's (OK, I skived off and didn't re-read the Griffon models
) along with the Merlin engine manuals and "E&M" equivalents for the Merlin I/II, III, XII, XX, XLV, 45M, 50, 50M, 60, 61, 70, 71... while researching the WOP3 Spitfire I/II....Also 35,000 General Assembly (Engineering Drawings) provided the dimensions, placement and characteristics of every piece that needed modelling (for instance, the diametre of the cooling vent hole
and the length, angle of bend and degrees of movement of the Mk I undercarriage pump handle.
That is the sort of research and detail that has gone into the WOP 3's and that tradition continues with the Mustang...oh..damn, sorry, forget that..not allowed to talk about the M.U.S.T.A.N.G. in front of the C.H.I.L.D.R.E.N...
